  • This invention relates to prosthetic acetabular cups and to methods of making them.
  • Open pores at the surface of the implant are rooms for bone trabeculae formation and deep interdigitation. This mechanical interlocking is able to provide long term attachment after complete dissolution of the hydroxyapatite coating.
  • Composite/plastic materials are not X-ray lucent.
  • a prosthetic acetabular cup which has a bearing surface layer made from a composite material such as, for example, PEEK resin having at least 20%-40% short carbon fibers and a backing layer or layers providing a barrier and/or porosity and/or roughness.
  • a bearing surface layer made from a composite material such as, for example, PEEK resin having at least 20%-40% short carbon fibers and a backing layer or layers providing a barrier and/or porosity and/or roughness.
  • the backing layer is made from metal and is coated with a bioactive material.
  • the backing layer could also be made from PEEK resin to produce a barrier between the composite material or the surface layer and the bone cells in which it will be used.
  • the acetabular cup outer layer may be made of a bioactive material such as hydroxyapatite with or without bone morphogenic proteins.
  • the method of forming the prosthetic bearing surface has as a first step injection molding and bearing layer of PEEK resin having 20%-40% carbon fiber to form an inner bearing surface. Then metal particles are sputtered on to the outer nonbearing surface of the molded bearing to form a porous backing layer and then hydroxyapatite is sputtered on to the metal backing layer to form an outer surface of the prosthetic bearing element. PEEK may be plasma sprayed on the outer surface of the bearing layer prior to applying the metal layer.
  • the metal particle size may be varied to form an interconnected porosity which increases towards the outer surface as the layer is built up. The particle size may increase from smaller to larger to form the increasing interconnected porosity.
  • a mixture of metal particles and hydroxyapatite particles may be sputtered on to the backing layer to form the interconnected porosity.
  • the bearing layer has about 30% short carbon fibers.
  • the bearing layer may be preformed and the backing layer or layers may be applied by sputtering and/or chemical or plasma deposition.
  • the metal utilized for the backing layer or layers is preferably selected from the group consisting of titanium, titanium alloy, tantalum, niobium or cobalt chrome alloy.
  • bioactive material encourages the bone cells apposition and development; rough surface and/or porous surface provides structure for mechanical fixation after dissolution of the bioactive layer; composite material provides elasticity for natural load distribution to the bone, and also provides highly wear resistant bearing surface; and the benefits of the metallic material, when provided, is to provide an opaque marker for X-rays and a proven biological interface for good bone ongrowth/ingrowth.
  • the bioactive material can be hydroxyapatite (HAP) and/or bone morphogenic proteins (BMP).
